1.2.1 Data Synchronizer Server Requirements

Adequate server memory depending on the number of users/devices supported by the Synchronizer server

4 GB RAM to support approximately 300 users/devices

8 GB RAM to support approximately 500 users/devices

45 MB of disk space for the Synchronizer software

200 GB of disk space recommended for data storage during system operation

Data storage disk space varies widely depending on the amount of data being synchronized, the number of users participating in synchronization, the logging level for Synchronizer log files, and other variables specific to your Synchronizer system implementation.

The largest consumers of disk space are the Synchronizer database (/var/lib/pgsql) and Synchronizer log files (/var/log/datasync). You might want to configure the Synchronizer server so that /var is on a separate partition to allow for convenient expansion.

Another large consumer of disk space is attachment storage in the /var/lib/datasync/syncengine/attachments directory.

NOTE:The 200 GB recommendation is appropriate for a large Synchronizer system of approximately 500 active mobile device users. A Synchronizer system with substantially fewer users requires substantially less disk space.

If PostgreSQL is not already installed on the Synchronizer server, the Mobility Pack Installation program installs it for you.

Time synchronization among servers

For the most reliable synchronization of time-sensitive items such as appointments, the Synchronizer server and GroupWise servers should have their time synchronized as closely as possible. This is especially important on virtual machines.

1.2.2 Directory Service Requirement

Lightweight Directory Access Protocol (LDAP) v3

Any version of Novell eDirectory fills this requirement. Other LDAP directories are not currently supported.
